Coral propagation holder with adjustable shelves

ABSTRACT

A coral holder resides in an aquarium and includes shelves with holes which accept coral plugs. The coral plugs are small round tables with cylindrical stems extending down from the table. Hobbyist take adult size living corals and “frag” them (i.e., cut the mother colony and break off a small section) and glue the coral fragments to the coral plugs. The coral plugs are inserted into the holes on the shelves providing a coral display. The holder includes a center section, a fixed top shelf and adjustable shelves. The adjustable shelves extend out sides and front of the center section and are adjustable allowing the aquarium owner to adjust the adjustable shelves accordingly to their needs (i.e., for the number of coral plugs). The positions of the shelves are fixed by inserting the coral plugs through the fixed top shelf and through the adjustable shelves.

BACKGROUND OF THE INVENTION

The present invention relates to coral displays in aquariums and in particular to a display with adjustable shelves which may be fixed in a desired position.

Coral is often displayed in aquariums providing a colorful display of various natural shapes. Some aquarium owners collect a variety of different coral types and attach each to a common holder. Unfortunately when the aquarium owner desires to add to his display, he may reach a point where there is no additional room for added coral types.

BRIEF SUMMARY OF THE INVENTION

The present invention addresses the above and other needs by providing a coral holder which resides in an aquarium and includes shelves with holes which accept coral plugs. The coral plugs are small round tables with cylindrical stems extending down from the table. Hobbyist take adult size living corals and “frag” them (i.e., cut the mother colony and break off a small section) and glue the coral fragments to the coral plugs. The coral plugs are inserted into the holes on the shelves providing a coral display. The holder includes a center section, a fixed top shelf and adjustable shelves. The adjustable shelves extend out the sides and front of the center section and are adjustable allowing the aquarium owner to adjust the adjustable shelves accordingly to their needs (i.e., for the number of coral plugs). The positions of the shelves are fixed by inserting the coral plugs through the fixed top shelf and through the adjustable shelves.

In accordance with one aspect of the invention, there is provided a coral holder which taking advantage of a synergistic relationship between displaying coral attached to coral plugs, and using the plugs to secure adjustable shelves used to hold the plugs. A center section receives shelves inserted into slots and grooves. The shelves include an array of holes sized to receive coral plug posts reaching down from coral plug tables. The posts both position the coral plugs on the holder, and also engage the shelves to fix the shelf positions. When an aquarium owner desires to display additional coral, the coral plugs retaining the shelves can be removed, the shelves adjusted to provide additional position for coral, and the plugs repositioned to again engage and retain the shelves.

In accordance with another aspect of the invention, there is provided a coral holder which includes a center section, a fixed top shelf and adjustable shelves. The adjustable shelves extend out the sides and front of the center section and are adjustable allowing the aquarium owner to adjust the adjustable shelves accordingly to their needs (i.e., for the number of coral plugs).

In accordance with still another aspect of the invention, there is provided a coral holder which includes adjustable shelves which remain stationary in the center section after adjustment. The adjustable shelves are retained in the center section by lining up the holes in the adjustable shelves with holes in the fixed top shelf, and inserting a coral plug through both holes, the stem of coral plug providing a locking mechanism while still being utilized to hold a coral frag.

In accordance with yet another aspect of the invention, there is provided a coral holder which includes top shelf fixed to the center section and cannot be moved. The middle shelf and lower shelf are adjustable forward and rearward and the side shelves are laterally adjustable. An additional fixed bottom shelf may be provided and coral plugs may be inserted through the removable shelves and into the fixed bottom shelf to hold the moveable shelves in place.

In accordance with still another aspect of the invention, there is provided a coral holder which includes a fixed rear panel for bracing and holding two sides of the center section, and includes holes so water current is allowed to pass freely to prevent dead zones under the holder.

In accordance with another aspect of the invention, there is provided a coral holder which may rest on the floor of an aquarium, or may be held to an aquarium wall by sandwiching the aquarium wall between magnets. The magnetically retained embodiment includes the adjustable shelves and removable top shelf, but not necessarily the removable bottom shelf.
